IMPROVEMENT IN HET-RADIATORS.

The Schedule referred to in these Letters Patent and part ofthe same.

To all whom. t may concern.-

Be it known that I, S. MONTGOMERY PIKE, of Cincinnati, in the county ofHamiltomand State oi Ohio, have invented a new and improvedHeat-Radiator; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same,

, reference being had to the accompanyingdrawings,

making a part of' this specification, in which- Figure l is a plan orltop view of myiuvention,

Figure '2 is a perspective view of the same.

Similar letters of' reference indicate like parts.

My invention consists in the employment of thin solid flanges, a part ofwhich flanges are arranged and cast on one side of a steam, fire, orhot-water heatingpipe, at right angles with the said. pipe, and a partof which are arranged and cast at an yoblique angle with said pipe, thebase of each flange on each side being opposite the space between theflanges on the opposite side of' said pipe, each end of' which pipe isprovided with transverse arms, which arms are provided with a tenon onone end, and a socket on the other, so that a number of radiators canthus easily and quickly be packed together.

'c designates the main or centre pipe;

b b designate pipe-arms at each end of the main pipe a.

On one end of each arm, b, is a socket, e, to receive the other ortenoned end d.

By this means a number of' radiators can ybe put together, the small endd entering the socket e.

I construct the main pipe a three inches in diameter, with an insidediameter of two and one-half inches. The pipe-arms 7) b are of nearlythe same size. v y

The flanges e, I construct three and one-half inches by seven inches,and about One-half of' an inch thick at'the base, and make them taper asthim as can be convenient-ly cast on the Opposite edge. I cast theseflanges e on the main pipe a, about onehalfof an inch' apart at thebase, and setting them with said base nearly even with the centre of themain pipe a, the

and form afsquare body of fiangesseien-inches square,

with the area or outer surface twelve times greatery thanA the area ofthe steam or inner surface.

The object of the flanges and theirarrangement is to present as muchheated surface as' possible to the air, while I confine the steam inthecentre or heart of the same, where it will keep hot a long timewithout'condeusing as fast as it would if allowed more room. As thecentre of this column of steam Amust contain latent or insensible heat,it is developed and absorbed by the iron. y v Y As the outer surface ofthe steam-column is conde'nsed to water, it keeps'np the temperature onthe outside lsurface sufficient to warm the air properly,

without drawing as much fresh steam 'from the boiler, and consequentlysaving a large amount of' fuel.

When several of these radiators are connecteththey are boxed andsupplied with steam in the usual man:

ner. If desired, iu stocking these radiators, -part of them might beplaced with the oblique flanges pointing in .one direction, and'otherspacked with the oblique ilangespointing in the opposite f direction, theobject being to turn heated air passing through them toward differentflues.

The object of placingY each flange e opposite, space is to morethoroughly break up and warm the current of air passing through themthan it .would if the flanges were placed opposite each other.

ByV my invention,.1 produce an varticle fora radiator which is cheaplyand easily cast in one piece.' The central or main pipe is only oneventire piece, while the connecting pipe-arms 11.71 areconvenient ofaccess,

and easily packed, whereas, in some radiators, the

large cent-ral pipe is packed' at a great expense,'and not always tight.It is not only cheaper. in first cost than any other radiator, but byactual usehas provedI to produce the largestamonnt of' heat in'proportions Ito the fuel used'.

I do not claim, broadly, the use of flanges in radiators, unless thesame are constructed and combined as described.,

What I claim as' new, and desire to secure by Letters Patent, is-

The radiator, consisting of pipe a and flanges, the arrangement of saidflanges in the position and'angles herein shown and described.
